Lets begin with Linear patterns. They are probably the easiest to recognize because the change is related to slope of a line.

Nth term Patterns- look at the difference between the terms- if the differences are constant, the expression is linear- if the differences are not constant, look at the differences
between the differences- if the second differences are constant, then the expression
will be a quadratic expression

1st Find the difference for each consecutive term
14 – (-1) = 15 39 – 14 = 25 74 – 39 = 35119 – 74 = 45

Since the differences are NOT CONSTANT, we need to find the difference between the differences we just found…
